Slim Folding Thermometer Holder for Traeger P.A.L. Rail

Slim Folding Thermometer Holder for Traeger P.A.L. Rail

A two-piece holder that keeps a folding thermometer within reach while grilling, with a slimmer pocket, a separately printed rail clip, and recessed hardware.

I made this after printing a single-piece holder in ASA-CF and having the hook break during installation. The original pocket was also too large for my thermometer. This redesigned version has been printed and test-fitted successfully in ASA-CF.

Fit and Features

Designed around a closed thermometer measuring 43 mm wide × 17 mm thick × 175 mm long.

- Pocket interior: 45 mm wide × 19 mm front-to-back × 80 mm deep.

- Separate rail clip: prints on its side rather than upright with the holder.

- Recessed screw heads: sit below the clip’s rail-facing surface.

- Recessed nuts and screw tips: keep the thermometer pocket clear.

- Outside Allen-key access: no need to tighten screws inside the narrow pocket.

- Bottom drain slot: allows water to escape.

The rail used for this design measured 62.25 mm high × 9.25 mm thick. Check your measurements before printing. This is sized for a slim, Thermapen-style folding thermometer—not every thermometer model or rail variant.

Printing

Print one of each part in ASA-CF:

- box.stl: upright, with the opening facing up.

- clip.stl: on its side, as already oriented in the supplied file.

Both parts have been successfully printed and fitted in this material. Inspect your sliced layers and use settings appropriate for your printer and filament.

Hardware and Assembly

Required:

- 2 × M4×12 socket-cap screws.

- 2 × M4 hex nuts.

- A matching Allen key.

The head recesses are 8 mm diameter × 4.4 mm deep, accommodating the tested 4 mm-tall screw heads below the surface. Check your screw-head diameter. M4×8 screws are too short; flat-head screws are not intended for these recesses.

1. Insert the nuts into the pockets inside the holder.

2. Position the clip against the holder’s flat back and align the holes.

3. Insert and tighten the screws from the outside, rail-facing side before mounting on the grill. Tighten snugly without overtightening.

4. Confirm that the heads, nuts, and screw tips remain recessed, then gently fit the assembly onto a cool rail. Do not force it.

Keep the holder away from the hot barrel and flame, and check your filament’s temperature limits. Fit has been tested; long-term heat and load performance have not.
